CLOSURE Application filed May 25,

This invention relates to improvements in closures and has particular relation to closures which forvone reason or another are larger in diameter than the openings which they are adapted to close. More particularly, the invention relates to closures of this type which are adapted for releasable connection A more specific object of the present invention is the provision of a closure of the type described which is neat and pleasing 1n appearance, strong or sturdy in character, and economical to manufacture. Further objects of the invention are in part obvious and in part will appear morein detail hereinafter. 7 7 r In the drawing, which represents one suitable embodiment of the invention, Fig." '1' is a sideelevation of a closure applied tothe tubular filler neck of a'tank or receptacle; Fig. 2 is a central vertical sectional view thereof, the section through the closure being. on the line 24-52, Fig. 3; Fig-3 is a bottom plan'vlew of the closure; Fig. 4 is a top plan viewof the filler neck; and Figs 5is a central vertical sectional view of said neck on the line 5+5, Fig. 4. Y

As here illustrated, the o ening to be closed is the opening 1' in the tu ularfillerneck 2 of a'receptacle 3, said neck being an integral part of said receptacle or separate therefrom and suitably secured thereto, the present neck being provided with an annular-base flange 41 for securement purposes. Said neck -1s pro- 'vided at its upper end withan inwardly ex-.

tendingflange 5terminating ina depending flange 6. At three circumferentlally spaced points, parts of flanges 5 and 6 are cut away to provide passage-ways 7 for the locking fingers of the closure, as will later appear. Thecutting away of said flange parts pro-.

vides three depending flange portions 6, and the lower edge of each of said flange por shown, each cam surface is provided at its rear end with a dwell or seat 9 to receive a closure finger when the closure is in fully locked position on the filler neok, and each:

flange portion 6 is provided adjacent its dwell with a depending projection 10 to limit readily understood.

rotary movement of the closure, as will be The closure here'illustrated for filler neck opening 1 comprises an outer wall and an inner wall separated to provide an air chamber 15 therebetween. The single member forming the outer Wall includes a" dome-shaped portion 16 and a depending marginal skirt portion 17. The single member forming the inner wallincludes a cenclosing the" tral dome-shaped portion 18, an intermediate portion 19 and a depending marginal skirt portion 20 non-rotatably secured to the skirt portion 17' of the outer wall member,-such as bya crimping operation.

The closure inner wall member is providedwith three fingers for detachable locking engagement wit-h the cam surfaces 8 of the filler neck, and in the present embodiment of the invention, resilientfingers 22 are formed by.-

shearing the intermediate portion 19 of the inner wall member. Said fingers extend downwardly and outwardly from the base of the dome-shaped portionl8 of said member and terminate in transversely; curved end portions 23which are adapted tolyieldingly engage the cam surfaces '8of the filler neck; Preferably'and as shown, said fingers are provided at theirbases with suitable re-en forcing or bracing means, such as the webs 24. The closure is applied to the filler neck by passing the free end portions 23 of the looking fingers down through the three passageu ways 7 of said neck and then imparting clockwiselrotary movement to the closure so as to cause its locking finger portions 23 to ride upthe cam surfaces 8 of the neck until said finger portions strike the stop projections 10, at which time said finger portions rest upon the dwelis 9 at the rear ends of said cam surfaces. To remove the closure, it is only necessary to impart counter-clockwise rotary movement thereto which will cause the closure finger portions 23 to leave the dwells 9 and ride down the-cam surfaces 8 until they reach the passage-ways 7, at which time the closure can be readily lifted from the neck.

In order to enable the closure to be easily and quickly positioned in proper position relative to the filler neck for connection there to, the closure is provided with suitable means for centering the same relative to said neck. In the present embodiment of the invention, said centering means comprises three circumferentixlly arranged depending flanges 29 formed by shearing the metal ofthe intermediatesportion 19 of the closure inner wall member. When the closure is applied to the filler meek, said depending flanges enter the open'inglof the filler neck and engage the inner surfaces of the depending flange portime (ithereof, thereby centering the closure relative to the filler'neck and enabling detanhahlelooking connection therebetwcen to beiaasily and quickly effected.

lfdesired an annular gasket of cork or other yielding material maybe interposed betweenthe topfiangefi of the filler neck and the intermediate portion 19 of the closure innor will member, thereby more effectively i the filler neck opening. Said gasket would-surround the three centering flanges 99 and therefore cover the three slots 32 3 formed in theinner wall portion 19 by the shenrimgoperation, such position of a gasket heing'indicated by the dotted line 33 in Fig. 3. -.However,=when the closure is connected to the fihler neck, the closure air chamber 15 isventedltothe inside of the filler neck and hence to the inside of the container 3 by the Openings 34 in theclosure inner wall formed asia rosult ofthe shearing operation to provide the closure lockingfingers. To vent the closure air chamber to the outside atmosphere,,one or: more openings 36 may be pro Wided'in the dome-shaped portion 16 of the closure outer wall member, as will be readily understood.
